PPE has installed the UK's largest O-ring moulding machine, producing O-ring seals up to 2m in diameter for marine engine, oil and gas, nuclear and power generation industries worldwide.
Size matters at high performance seals specialist Precision Polymer Engineering (PPE) where the company has installed the UK's largest O-ring moulding machine, producing O-ring seals up to 2m in diameter for marine engine, oil and gas, nuclear and power generation industries worldwide.
Weighing in at 122 tonnes, the GBP 500,000 variable-down-stroking press is capable of exerting between 50 and 500 tonnes of pressure.
This, in conjunction with a vacuum chamber encompassing the mould tool to eliminate air traps, produces exceptionally accurate moulded O-rings and custom parts, including discs, in depths up to 380mm.
Designed to repeatedly produce precision moulded parts, the PPE moulding machine features a sliding double platen for easier tool fitting and increased manufacturing productivity - as one seal is being moulded another is being prepared.
"Manufacturing large O-rings and custom parts at a consistently high level of repeatability calls for the kind of precision moulding that only a machine of this size can offer", says PPE Managing Director, Peter Cloney.
